Summary

CARCASSES WERE PLACED IN BAGS OF LOW GAS PERMEABILITY AND EITHER FLUSHED WITH NITROGEN OR FILLED WITH CO2. CO2 SIGNIFI-CANTLY REDUCED THE GROWTH OF GRAM-NEGATIVE OXIDATIVE AND FERMENTATIVE BACTERIA. THE MEAN PH OF THE PURGE FLUID FROM BOTH SETS OF CARCASSES WAS 6.3. WHEN PRIMAL CUTS PREPARED FROM STORED CARCASSES WERE HELD AT 278 K (5 DEG C), OFF-ODOURS WERE SLOWER FOR THE CARCASSES STORED IN CO2. WHILE THE AEROBIC SPOILAGE FLORA OF LOINS FROM UNSTORED CARCASSES WAS COMPOSED MAINLY OF B. THERMOSPHACTA AND OXIDATIVE GRAM-NEGATIVE BACTERIA, THIS LATTER GROUP BECAME A SMALLER COMPONENT OF THE SPOILAGE FLORA OF THE LOINS THE LONGER THE CARCASSES HAD BEEN STORED.
